ABSTRACT:
A power line communication apparatus is provided with an auto gain detector that detects a gain fluctuation of an AGC (Auto Gain Control) circuit that automatically adjusts a gain of a received signal; a retry ratio calculator that calculates a ratio of retry based on output from an ARQ (Automatic Repeat request) unit that detects an error in the received data and issues a repeat request; and a transmission rate calculator that calculates a transmission rate based on output from a channel estimation unit that calculates a CNR so as to estimate a transmission status. A display displays a transmission status, including the detected AGC noise fluctuation, retry ratio, transmission rate and the like.
